DESCRIPTION
GPIO70~GPIO68 and GPIO59~GPIO52 output mode enable
1 = enable
0 = disable
NOTE: Output mode enable bits are valid only when bit
PT4CFG10-0 is configured as general purpose I/O mode.
Each port pin can be enabled individually by setting the
corresponding control bit.

PORT4 data output value
Writing data to this register will reflect the data value on the
corresponding port4 pin when it is configured as general purpose
output pin. And writing data to reserved bits is not effective.
